Customer Ratings & Reviews

Decent charging speeds, took it out for camping and worked well

This battery is little heavy, but it’s indispensable for travel. Would have given this five stars if it had come with its own cable for charging!

Great and good looking! last a long time and charges my devices fast

Good product, still my option. Best Buy ever, the excelent quality and working for long 12 mounths and i bought again right know.

Very good battery, I have charged the device and threw it in my purse for those times you suddenly need to charge your phone. It has sat for 6 months in my purse and when I turned it on today, it still had a full battery.

I usually get multiple charges. Just a bit heavy though.

Great power bank…especially for travel!.Worry free charge

This is an excellent product. I purchase it cause my old one didnt work anymore. Ive been having anker for a while. Theya re reliable, this is my 5th item i buy from this brand. I used it everywhere i go, its great for travel, its super fast charging, i charge my phone 3 times. I recommend this product

Bought this for my daughter in college. Like any other young adult in college, they spend most of their day in classes and they always run on a low cell phone battery. Since I bought this for her, the easy convenience of charging has kept her phone charged. Which makes me a happy father.

Wonderful power bank. Quick charge after charging iPhone. Will charge iPhone fully twice.

Excellent charger. Quick to charge and holds it's charge longer than expected.

I have been looking for a reliable battery charger and the Anker PowerCore II is exactly that. I don’t have to worry about losing battery life on my iPhone when I travel.

Great battery for everyday use. Charges your devices quickly and multiple times.

Charges phone so very fast, love it. To charge it fully, it takes a while so you need to plan ahead. This is great for my teenagers who insist on going around with 3% charge in their phone, even while traveling across the globe. This gives me piece of mind.

I did research on these battery chargers and decided on this one, with no regrets. I was able to charge my phone at least twice during my trip without charging the battery. I could have charged my phone a few more times. It was reassuring to have the battery with me as I was in airports for hours at a time.

This item lasted us an entire Europe flight from California and was a key source of power when we were in Europe. It was dependable, reliable, and I would trust this with my life! I couldn't say enough good things about this brick, I may ask it to be best man in my wedding, it was pure perfectly.

Amazing fast at charging and very stylish and compact

Does what it should. Holds a long charge and charges my devices fast.

Pretty good powerbank, it lasts 12 charges and it has fast charging

Worked well except was very heavy, better for if you are not on the move a lot, but it did recharge several devices well and recharged itself over night.
